Nano paint for ships and hospitals?

Ship in dry dock

According to the marketer of a new line of nano paint, this revolutionary product is a “non-toxic coating system which is able not only to stop the appearance of algae and fungal growth but also destroy antibiotic resistant bacteria found in hospitals and medical practices.”

Impressive performance

Whether for shipping or hospitals the paint seems impressive. The company claims the antibacterial paint could help solve the problem of hospital super bugs. Risks The product data sheet for this nano paint raises the spectre of a real pollution concern. It carries the warning, “do not allow to enter drains or watercourses” while other literature advises: “Clean tools and hands immediately after use with soap and water.”

A reader of NewScientist.com where this item appears wonders where that nano-contaminated soap and water will end up if not in drains and watercourses. And what’s the consequence of nano pollutants in the environment? Risk research needed. Read about the key risk research questions that we need answers to in this article, “What’s driving the nanotech revolution and what this means for safety.”

Safe Drinking Water

Safe Drinking Water, Lessons from Recent Outbreaks in Affluent Nations by Steve E. Hrudey and Elizabeth J. Hrudey Iwa Publishing, 486 pp.

Safe Drinking WaterContaminated drinking water killed and sickened people in affluent communities long before anyone heard of Walkerton’s Koebel brothers. University of Alberta water scientist Steve Hrudey says waterborne outbreaks will persist in wealthy societies long after the brothers are forgotten – unless the underlying problems of complacency, neglect, accumulating errors, bad judgment and poor practice in water treatment plants are properly dealt with.

Hrudey, who worked on the research advisory panel to the Walkerton Inquiry and collaborated with the Canadian Water Network on the issue, said, “Far too many people seemed prepared to write off Walkerton as being only the misdeeds of the Koebel brothers. If you draw all the attention to a few blunders, ignoring the bigger picture about why waterborne outbreaks have persisted, you aren’t going to get the right people to take ownership of the problem.” Continue reading
